It is not clear exactly how you are using the Page Template. Typically 
the page would have an img tag that calls a python script that calls the 
External Method. Remember the web browser fetches the image separately 
after the html has been received - so your img tag might look like this:
 and your getImage python 
script would look like this:

(type, encoding) = context.getMimeType(context.REQUEST.filename)
context.REQUEST.RESPONSE.setHeader('Content-Type', type)
context.REQUEST.RESPONSE.setHeader('Content-Disposition', 'inline;
return context.getDocumentCall(context.REQUEST.filename)
where getDocumentCall is the name of your External Method that calls the 
getDocument External Method and getMimeType is another External Method 
that looks like this:

import mimetypes
def getMimeType(filename):
return mimetypes.guess_type(filename)
and your own external method would look like this:
> ##parameters=filename

Re: Potential PythonScript bug (was: Re: [Zope] question about manipulating zcatalog query results)

[Ira Sher]

Dieter,
thanks. I'll take a look at that now. The folks at bug collection are
unable to reproduce the bug on 2.7.5, though, and so we're trying to
determine how else it might be occuring--Products would be my best
guess, as the Product list has changed (many are obsolete or simply
don't run on 2.7.5 when migrating from 2.5.1 (with products that have
been left on since 1.x...ug). The last version I had it running stably
on was 2.6.3, locally, and of the several products that have been
migrated out since then, PluginIndexes and ZCTextIndex I can't grab
from cvs (the versions I have crash the startup) as I get a 4k empty
tarball downloading with any browser...don't know if these should be
obsolete, too.

take care and thanks again for the suggestions

As zope doesn't run on Iron python the impact will be small. it's nice
for people that are forced to run .NET to be able to do it in Python
though. And it does marginally widen .NETs appeal, but only
marginally. :-)

A role that does not fit well into the group concept is the "Owner" role.

You may use the ":default" specifier with a hidden variable

The strange thing is that I can do:

return [o.id for o in container.Catalog()]

without a problem.

However, I am still using Zope 2.7.2 -- the version
before the last security shakeup...


If your script does not need security checks, than
my "TrustedExecutables" might help you. It provides
"PythonScript"s without any security restrictions -- and
especially without the need for "_getiter_".

Sorry for the delay.  You would likely get quicker response if you had
replied on the list.

The DBTab product is not compatible with Zope >= 2.7.  Its functionality
has been moved into the core, and is now configured using the normal
'zope.conf' config file (note that the sessions machinery configures the
temporary storage mounted at '/temp_folder' this way).

Sure it is, but the problem is that supporting it in future versions
of Zope very well may need changes in Zope itself.  Changes that is
*far* from trivial. So I think it's mostly a question of "Should Zope
corp put down the effort to keep ZClasses working", because, most
likely nobody else can...

If you are going to use Plone I can't offer advice - I have looked at 
Plone on three separate occasions, and recently read The Definitive 
Guide to Plone, and have stil decided not to use it. I only say this to 
make it clear that many applications are built without CMS and Plone.

Two separate tables with User information is awkward! The user folders I 
know of expect user information to come from one source. So you either 
have to create two folders, each with its own acl_users (provided by one 
of the User Folder Products), or you have to hack the User Folder 
product to put in a Union select statement in place of a simple Select.

You have not said whether the people in the different districts do 
completely different things with different forms, or identical things 
but specifying the district. If the former then it is no big deal to 
create the folders manually, although it can be done programmtically. 
You could set a Local Role equal to the district name and get that role 
for users from the database. That way, users can only enter their own 
district folder. If the latter, then you could retrieve the Username and 
District from the User object for use in the forms (include the District 
as a role).

Try working on the rest of your application to build up ZPT and Python 
experience. As I said, managing users is tricky. Also, be aware that 
Zope experts advise developers to produce file system based Products. 
There are lots of simple Products that you can use and browse the code 
to see how they work.

From there you decide your
zope folder structure. It could be like this:
site_home
|__acl_users
|__district1
|__district2
or like this:
site_home
|__district1
||__acl_users
|__district2
||__acl_users
In the second case you would not have to worry about asking the user for
the district name. In the first case you would get a district name or a
user defined role for that district from a supplementary data source,
like a database.

So i think 2nd structure is abetter fit.
Now the qusetion is how do build this district user folder structure
using the database?
Hope not manually, because there are 22 districts and about 15 users
in each of them pluys head quarters.

A combination of exUserFolder and MySQL would do.

i don know about them, something like mysqluserfolder or
simpleuserfolder components ?

You can get information on the logged in user (Username and Roles) from
the User object, so you don't need to expicitly use sessions at this
stage. You should certainly not store passwords - that would be a 
serious breach of confidentiality.
Maybe you should say what you do with the District parameter after the
user has logged in.

I dont need the password but do need the username and district for
following pages to decide the access rights and the stores available
inthe districts , also for some report labels.

Re: [Zope] RSS feed: post-processing?

Sorry Eva,
You'll need to explain your problem more succintly for people to be able 
to help. If you really do need to scrape the urls from the text, then a 
combination of python's xml handling and regular expressions is probably 
what you're after, best done in an external method and not a python

Hello,
I've been puzzling over something but can't figure out a solution. I  
have an RSS feed providing the content behind all the links on this  
page: http://demo.plinkit.org/interestsideas/goodreads/booklists.

There's a nice bookmarklet tool in the world called LibraryLookup that  
lets you check whether a book you find on Amazon or something is in  
your library's catalog by scraping up the ISBN and launching an ISBN  
catalog search. It's a javascript, really. I thought I would adapt this

to create a little add-on for the stuff the bestsellers RSS brings back
to my site. What I need to do is pluck out the ISBNs in the links on a  
page like this one:  
http://demo.plinkit.org/interestsideas/goodreads/sinList?synmap=Hardcove
rFiction

The ISBNs are all in the URLs for the book titles  
("isbn=Some10digitNumberHere"). How would I look for a piece of text in

that shape, i.e., isbn=5893193390, then, if it's there, copy and paste  
that piece of information into the LibraryLookup javascript I have. The

end result should be that, if there's an ISBN in a feed result, an extra
link  
appears for each entry that says something like "Check the catalog,"  
which you can click to look that book up in your own library's catalog.

I've been staring at the template that formats the RSS feed to figure  
out whether any TAL expression would work for this. I've been playing  
with a short Python script, then wondering how to call it within that  
template, but I think I have to use regular expressions to do it.

I'm sorry to be so lost on this, but I guess I am. I'd love to do  
something cool like this for our little Plinkit libraries. Can anyone  
help? I'll take anything from a broad strategy to actual code snippets  
(I'm a terrible programmer but a good librarian).

Thanks

I have noticed that the Plone package on Debian is or was somewhat broken, but 
there was a notice about that on the Plone website (download page) which has 
disappeared. For me that looked like this problem was fixed by the package 
maintainer.

Unfortunately still, after installing Plone (and implicitly thus Zope 2.7) 
Zope did not want to come up, saying:

Did you read the debconf-pages that were presented to you during the
installation of zope and plone? I guess not, because else you won't
ask that question. Short answer: create a new Zope instance using
mkzope2.7instance, check it's config and remove the '#' on the lines:
products /usr/lib/zope2.7/lib/python/Products
products /usr/lib/zope/lib/python/Products
products $INSTANCE/Products
To have Zope 2.7 find the Plone Product. The documentation of Zope and
Plone will explain why you need to do that.

 Zope starting all instances
 '*' is an old/purged instance, not started

Looks like Zope2.7 finds an old 2.6 instance, but I'm not sure...

Re: [Zope] script or external method ?

[Lennart Regebro]

Congratulations: You immediately ran into a limitation of Python
Scripts, and then equally quickly into one of external methods. That's
good, because that means you don't get stuck into the wrong way of
programming. :-)

The "right" way of doing Zope development is with filesystem python products.

Not Python Scripts, not External Methods, not ZClasses and not DTML.
Each of these may have their place, the best generic way is file
system products. I don't know what is the best starting point
nowadays, but I think doing the Boring Product tutorial still seems
popular:

http://www.zope.org/Members/gtk/Boring/HowTo-Boring


For Zope development there is today basicaly two and a half different
paths to go:

One: Zope2 (which is what you started with now). This gives you access
to loads of products and a huge community to support you. This is the
right way to go if you are interested in using Zope for creating a web
site. Primarily you have a whole bunch of different content management
systems to select from (CPS, Plone and several more) to get you
started. There are also blog software and wikis and stuff that can be
used with these.

Two: Zope3. If you are more interested in developing the system, and
you want a good development framework as your reference to j2ee
indicates, then Zope 3 may be the path for you. It doesn't have that
much of all this modules like Zope2 does, but the development
framework is SO much better. I sincerely doubt there is anything even
remotely this cool anywhere else in the webworld.

The drawbacks of Zope 3 is that you'll have to develop more yourself,
and it is a bit harder to get started with.

Two and a half: Five/Zope2.8. This is a way to use the Zope3 framework
under Zope2. It's mostly of interest for people who have legacy
products under Zope2.

While i was developing my first Zope application i

Well, 2 are the questions:
First, what i've to do to get service variable like
like container, context, request, etc.. ?
Which are differences between script and external
method coding? i remember that the zope book
indicates only imports.
Python scripts (the TTW kind) have security restrictions and have 
special procedures for setting the name and the parameters of a method. 
(Via the TTW forms: notice that you don't write def methodname() et al.) 
There are also some special names bound, like context and so forth.

External methods are regular Python methods in a Python module which are 
made available to be used live in Zope. Just as in any Python method, 
you can get to the context in which it was called through the 'self' 
parameter, which you will define as the first param. This is the same as 
'context' in a Python script. So you can say::

  def getThisId(self):
return self.getId()
You can get the request like 'self.REQUEST'. The container can be found 
with self.aq_inner.aq_parent or something like that.

Alternately, you can allow modules in Python scripts. See 
zope/lib/python/Products/PythonScripts/README or 
http://svn.zope.org/Zope/trunk/lib/python/Products/PythonScripts/README.txt?rev=24563&view=auto

thanks so much Cliff.

I dint want to built customized login page in 1st place. Actually this
is a Govt. stores management site used in my state only bulit all in
ASP. I 've to convert this into a Zope and Plone version.
So i wanted to get it converted with minimun changes.
But now as you say i think I should go the way Zope does it . only
that i'm finding it hard to customize it in Zope.

So i think 2nd structure is abetter fit.
Now the qusetion is how do build this district user folder structure
using the database?
Hope not manually, because there are 22 districts and about 15 users
in each of them pluys head quarters.

i don know about them, something like mysqluserfolder or
simpleuserfolder components ?

I dont need the password but do need the username and district for
following pages to decide the access rights and the stores available
inthe districts , also for some report labels.

i dint get to know much about coding ZPT's and Script(Python) for them,
 from the ZPT refs and Zopebook. So wanted some simple working examples.
